I'm the owner and creator of the seed, an ISO file For a period of two or three days upload was perfect. But after a reboot of my SUSE 10.3, the state change for leech. I removed torrent without removing data, and I recreated it, check data integrity pass with no error, 100% OK. But my upload are now dowload, and I'm the guys with all the files...

Can I fix this without recreate .torrent file?

SUSE 10.3
ktorrent 2.2.1

First see whether upgrading to 2.2.7 will fix this.
